| 摘 要： | 为研究蒸汽压片玉米及膨化大豆混合日粮对荷斯坦公犊牛腹泻情况、血液生理、生化指标的影响,选择39头荷斯坦公犊牛随机分为3组,分别饲喂代乳粉(MR)、一半代乳粉+蒸汽压片玉米与膨化大豆的混合精料(HMCS)、蒸汽压片玉米与膨化大豆的混合精料(CS),饲养150d,记录犊牛腹泻情况,测定犊牛血液指标。研究发现,MR组的腹泻情况最为严重,腹泻指数为59.74%,其次是HMCS组,为15.13%,CS组最低,为1.03%;犊牛血液抗氧化指标表现为,CS组犊牛的过氧化氢酶、谷光氨肽过氧化物酶、总抗氧化能力均是最高。MR组丙二醛的含量显著高于CS组(P0.05),与HMCS组差异不显著(P0.05);MR处理组犊牛血清中一氧化氮含量显著高于CS组(P0.05),HMCS组的含量处于二者之间;血细胞分析结果为3个处理的白细胞、嗜中性粒细胞、淋巴细胞及单核细胞差异均不显著(P0.05),但CS组犊牛的白细胞数、淋巴细胞及单核细胞数在数值上均是最高;血清生化指标结果为,MR处理组犊牛血清的总胆固醇含量显著高于CS组(P0.05),而CS组犊牛血清的尿素氮、总蛋白及胰岛素含量显著高于MR组。CS组的谷草转氨酶活性、谷丙转氨酶的活性最高;CS组的IgM浓度显著高于另外2组(P0.05)。低密度脂蛋白、极低密度脂蛋白及高密度脂蛋白的含量在3个处理间差异不显著(P0.05),但CS组的数值均是最高的。研究表明蒸汽压片玉米及膨化大豆可以减少犊牛腹泻发生,提高犊牛血液抗氧化和免疫水平,并促进血液总蛋白合成。

| Abstract: | The objective of this study was to investigate the effects of the mixture of steam-flaked corn and extruded soybeans on diarrhea and blood parameters in veal calves.Calves (n=39) were randomly divided into three treatment groups with 13 calves in each group:Group 1,milk replacer (MR) group;Group 2,half of the amount of MR in treatment one plus other half of mixture of steam-flaked corn and extruded soybeans (HMCS);Group 3,mixture of steam-flaked corn and extruded soybeans (CS).All the calves were fed for 150 d,and their diarrhea and blood parameters were studied.The results showed that:Calves fed CS had the lowest incidence of diarrhea (1.03%) that calves fed HMCS (15.13%) and CS (59.74%);Compared to calves in HMCS and MR treatments,calves in CS treatment had the greatest activities of Catalase,GSH-PX,TAC;MR calves had the greatest values of MDA than HMCS and CS calves;Calves fed with MR had the greatest values of NO than in calves fed with CS,with HMCS calves taking the intermediate value;Calves fed with MR had the greatest values of Cholesterol than calves fed with CS.However,CS calves had the greatest values of serum urea nitrogen,total protein,and INS than MR calves;Compared to HMCS and MR calves,calves fed with CS had the greatest activities of GOP and GPT;The values of IgM in CS calves was greatest than in other calves.These data suggested that a mixture of steam-flaked corn and extruded soybeans provided ad libitum in better animal feed for improving blood antioxidant,immunity,and positively contributes to blood biochemistry indexes in veal calves. |
